A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket, which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, though the traditional shape is used for most non-commercial and many commercial applications.
An airship, dirigible balloon or dirigible is a type of aerostat or lighter-than-air aircraft that can navigate through the air flying under its own power. Aerostats use buoyancy from a lifting gas that is less dense than the surrounding air to achieve the lift needed to stay airborne.
An aerostat is a lighter-than-air aircraft that gains its lift through the use of a buoyant gas. Aerostats include unpowered balloons and powered airships. A balloon may be free-flying or tethered. The average density of the craft is lower than the density of atmospheric air, because its main component is one or more gasbags, a lightweight skin containing a lifting gas to provide buoyancy, to which other components such as a gondola containing equipment or people are attached. Especially with airships, the gasbags are often protected by an outer envelope.
The Bristol International Balloon Fiesta is an annual four day free festival of hot air ballooning in Bristol, England. Teams from the UK and other parts of the world bring their hot air balloons to the site and participate in mass ascents where as many as 100 balloons may launch at a time.
A hopper balloon is a small, one-person hot air balloon. Unlike a conventional hot air balloon where people ride inside a basket, there is no basket on a hopper balloon. Instead, the hopper pilot usually sits on a seat or wears a harness similar to a parachute harness. Hoppers are typically flown for recreation. These aircraft are sometimes called "cloud hoppers" or "cloudhoppers". However, these terms formally refer to the products of a particular manufacturer, specifically Lindstrand Balloons. Nonetheless, "cloudhopper" is used by many people as a genericized trademark, which refers to all craft of this general type. Most hopper balloons have envelopes that range in volume from 14,000 to 35,000 cubic feet and have a maximum flight duration of 1 to 1.5 hours. The two principal commercial balloon manufacturers today offering hopper balloons for sale are Cameron Balloons and Lindstrand Balloons. Most other hopper balloons are experimental aircraft designed and built by amateur constructors.
A thermal airship is an airship that generates buoyancy by heating air in a large chamber or envelope. The lower density of interior hot air compared to cool ambient air causes an upward force on the envelope. This is very similar to a hot air balloon, with the notable exception that an airship has a powered means of propulsion, whilst a hot air balloon relies on winds for navigation. An airship that uses steam would also qualify as a thermal airship.
Lindstrand Balloons was a manufacturer of hot air balloons and other aerostats. The company was started by Swedish-born pilot and aeronautical designer Per Lindstrand in Oswestry, England, as Colt Balloons in 1978. Lindstrand Balloons was known for its leading-edge engineering, which included sophisticated testing and production facilities.
Hot air ballooning is the recreational and competitive adventure sport of flying hot air balloons. Attractive aspects of ballooning include the exceptional quiet, the lack of a feeling of movement, and the bird's-eye view. Since the balloon moves with the direction of the winds, the passengers feel absolutely no wind, except for brief periods during the flight when the balloon climbs or descends into air currents of different direction or speed. Hot air ballooning has been recognized by Fédération Aéronautique Internationale (FAI) as the safest air sport in aviation, and fatalities in hot air balloon accidents are rare, according to statistics from the National Transportation Safety Board (NTSB).
Per Lindstrand is a Swedish aeronautical engineer, pilot, adventurer and entrepreneur. He is particularly known for his series of record-breaking trans-oceanic hot air balloon flights and, later, attempts to be the first to fly a Rozière balloon around the Earth – all with British entrepreneur, Sir Richard Branson. He is also the founder of eponymous Lindstrand Balloons hot air balloon manufacturer based in Oswestry, England.
Bristol is a city in south west England. Its economy has long connections with the sea and its ports. In the 20th century aeronautics played an important role in the economy, and the city still plays a role in the manufacture of aircraft. Bristol is also a tourist destination, and has significant media, information technology and financial services sectors. Reports released in 2018 showed that the city is growing exponentially with a projected 2.3 percent annual growth rate until 2020.
Virgin Balloon Flights, with headquarters in Telford, Shropshire, began flying hot air balloons in 1994 and its passengers are still flown in red and white balloons with the Virgin Group logo on the side of the balloon.
Don Cameron MBE BSc MA MIEE D.Eng FRSGS is a Scottish balloonist, and later founder of Cameron Balloons, the world's largest hot air balloon manufacturer. Don Cameron is one of the few aeronauts to be awarded the Harmon Trophy, as the 'World's Outstanding Aviator' in 1999.
Cardington Airfield, previously RAF Cardington, is a former Royal Air Force station in Bedfordshire, England, with a long and varied history, particularly in relation to airships and balloons.
The history of ballooning, both with hot air and gas, spans many centuries. It includes many firsts, including the first human flight, first flight across the English Channel, first flight in North America, and first aircraft related disaster.
Kubicek Balloons is a Czech manufacturer of hot-air balloons and airships, the sole such manufacturer in Central and Eastern Europe and one of the largest in the world. From its factory in Brno the company ships its products worldwide.
Events from the year 1987 in Scotland
On 7 January 2012, a scenic hot air balloon flight from Carterton, New Zealand, collided with a high-voltage power line while attempting to land, causing it to catch fire, disintegrate and crash just north of the town, killing all eleven people on board.
On 23 August 2012, a hot air balloon on a commercial sightseeing flight crashed in stormy weather on the Ljubljana Marsh in central Slovenia, killing 6 of the 32 people on board.
The Cameron D-96 was the first hot air airship, a powered, steerable lighter-than-air craft carrying two or three crew marrying the elongated envelope of an airship with the externally localized heat source of a modern hot air balloon. It was designed and built in the UK and first flown in 1973.
Dr Janet Folkes was an academic from Nottingham, who held multiple ballooning records. She died in 2012 from breast cancer.
